This question arises from here where the OP discusses about Rushed Proposals, in this case for the crypto currency, IOTA.

My question is of a slightly similar nature in that it focuses on Blockchain in general. For those who are not very familiar, Blockchain is the underlying technology for Blockchain-based Cryptocurrencies. Common sense would dictate that it is good to have a Stack Exchange for Blockchain Technology and one for cryptocurrencies in general, especially since they might have similarities that can help solve problems across different blockchains.

If you look here, at a list of available currencies, I think you'll agree that the situation is going to get out of hand, with a stack exchange site for every coin that pops up, especially if they are approved in a moment's notice.

Would it not be better to unite all cryptocurrencies under one Stack Exchange site? CryptoCurrency?

iota hasn't been "approved in a moment's notice". It is stuck in Commitment phase and will be there for a long time because it lacks the support of experienced SE users. NEO will be in that position too. This isn't a bridge that a rushed proposal can cross easily.

Bitcoin and Cryptocurrencies is a question and answer site for cryptocurrency enthusiasts. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about Cryptocurrencies such as Bitcoin, Namecoin, Litecoin, Ripple, ZCash, Dogecoin, and NXT.

But I agree—it's getting silly to have a new Q&A site for every popular cryptocurrency when the expertise is very similar for most cryptocurrencies. That's why we don't have a "C Stack Exchange", and a "Python Stack Exchange"—it would become infeasible and it's likely that someone might be interested in both.

Does it make sense to propose the re-naming of the Bitcoin SE, in light of what you just said? In my opinion their should be two distinct SE. Blockchain, which is far more than just cryptocurrencies. And Crypto currencies. One might argue that bitcoin and ethereum are too big and they require an SE of their own. Perhaps then this Might Work. Blockchain - Bitcoin - Ethereum - AltCoin

@DottoreM It would make sense with the benefit of hindsight, but it's difficult to change when a site is created. It could be suggested on the Bitcoin meta site, though, if you wanted to ask if that had been considered.

I was just reading this link: bitcoin.meta.stackexchange.com/questions/662/… It seems pretty clear that altcoins are accepted in bitcoin.se, very much so. Would it be a solution to ban new altcoin proposals and instead redirect them to bitcoin.se to minimise the damage for future altcoins?

Stackexchange changed the name of programmers.SE to softwareengineering.SE not long ago.

@Philipp as well as Moderators.SE was renamed to CommunityBuilding.SE, so I guess this issue is way not that hard to fix.

Ethereum is special in the sense that it is more than just cryptocurrency.

@user930067 Would you mind expanding a bit more on that, please?

Many of the more popular cryptocurrencies are platforms for development, not just digital assets. The assets are a part of the platform.

That being said, StackOverflow has been great as a general programming site that supports different programming platforms in one location. Through the use of tags, I think a general cryptocurrency site could work.

No, clearly not. I've been following the Ethereum proposal from early stages and was moderator pro-tempore on Ethereum through the public beta until we recently graduated to a full site.

And there were all these people rolling eyes, and telling us Ethereum questions are well on topic for Bitcoin Stack Exchange. At some point, Bitcoin even reconsidered to change the scope to Blockchain or Cryptocurrencies to be more inclusive. But they never did.

And here is why: Because Stack Exchange sites only work out for certain technologies with dedicated communities. Ethereum introduced a full stack of new programming languages and even a new programming paradigm. It quickly gathered developers from all over the world curious to learn the new concept and the site was one of the most active communities during an early public beta, with up to 100 posts per day.

Now, imagine, there is a site in the network called Bitcoin, or even Blockchain, and 90% of the questions are about Ethereum. What would you do? First of all, most of the users would feel misplaced, repeatedly asking highly specific questions on a site not really dedicated to the topic, they are not programming blockchain or touching Bitcoin at all. It's an absolute natural move to create something clearly dedicated to the topic. Similar to Ubuntu having it's own site even though there is a Linux Stack Exchange.

And Area51 is the perfect place to test whether a new community is worth to have it's own site in the network. The process of proposal, definition, commitment, private beta, public beta, and final graduation is nothing I would describe as something that's approved at moment's notice. It's long, winding, and stony road. And every community deserves a chance to test the waters. Who remembers all skeptics that said Ethereum will fail in private beta?

Good luck IOTA, which is -by the way- neither a cryptocurrency, nor really a blockchain.

Because Stack Exchange sites only work out for certain technologies with dedicated communities. As another moderator and someone with years of experience on the Stack Exchange network, this is completely false. If your statement was correct, then sites such as Super User, Stack Overflow, Aviation, Photography would not exist right now.

I do not see that there is a real need for an "all Currencies" group/page. They differ way too much and it would, in my humble opinion, lead to too much noise and way less real information transported.
You see this in so many forums, where every discussion then just goes in all directions, and in the end, it is all just noise, one that you would get anywhere/everywhere exactly with the same noise.
So I see a benefit, that the information traded gets a higher value.

Using experience from fora, especially that "discussions then just go in all directions" is not relevant to Stack Exchange. There is a fundamentally different structure here. Your overall criticism is also invalid - the progenitor site was Stack Overflow, which covers all programming languages in extreme depth.

Non topic related discussion should be deleted, social networks are correct place for such

I think here some methods from some exchanges could be used. Some exchanges have restrictions like: a coin already must be active since min. 1 year. That way dead projects and requests for some/most copy & paste projects are excluded. Trolls will always exist but stackexchange deals very good with that.

There are very good projects. What you see in getting out of control is the real interest towards the topic blockchain, which is by far bigger than just bitcoin. Until recently, bitcointalk was used for announcements. In start, most did think correctly, that it is a correct place as that is where people with interest to blockchain find each other. Bitcointalk itself is in no way demonstration of free speech or anything similar. The idea was to keep all altcoin projects in overview and if there are usefull develpments, those could be implemented to bitcoin. But on bitcointalk it got very soon out of control, moderators as well as site and domain owners do follow some very questionable agendas, resulting in many cases as a crime which nobody wants to investigate. This is the real reason why so many people who though they have communication platform on bitcointalk need to switch, as there is no better place to get into technical discussion, stackexchange seems to be perfect for that.

My suggestion for a long run would be anyway to create separate category called "Blockchain". There are very many blockchain projects outside and with time, which look now for some replacement of bitcointalk and similar questionable forums.

IOTA is the only crypto-currency based on the new Tangle-technology

I suppose we want to bundle Q&A's if they have much in common. There are different criteria according to which you can bundle topics. It is true that all crypto-currencies are based on a Distributed Ledger Technology. However, there are 2 such technologies out there (in the crypto-curencies space): Blockchain & Tangle (DAG). If you take business perspective as a criterion, then they are very similar, but from a technical perspective they follow very different principles. If IOTA was part of some Bitcoin- or crypto-StackExchange-Site, then users would have to specify #IOTA each time they ask a question, because it makes a difference (e.g. mining, transaction fees, blocks, ...).
In my personal opinion, a Stack-Exchange-Site called "Tangle" would be more sensible. Nevertheless, IOTA probably claims the technology the same way Bitcoin once did it. Therefore, it makes sense to call it IOTA.

I think the reasoning for a stack.exchange community for individual coins is really for the developers benefit. Yes, it would be good to have a place to discuss overarching questions like scalability, block distribution, etc. but those topics really don't warrant a Q & A session because they aren't specific enough to have sourced responses to technical questions.
